Duel of Meloch is a standalone game that combines mechanisms from two existing games, Scythe and Expeditions, into a 45-minute head-to-head clash. One player uses Scythe rules and components (including a new faction and player mat found here); the other player uses the Expeditions rules and components (including a new mech and upgraded card deck found here).

You can even play Scythe vs Scythe or Expeditions vs Expeditions duels if you own either of those games (or even just Invaders from Afar or Gears of Corruption, respectively).

The duel takes place in a tight space on a new double-sided map—only 10 locations and 2 lakes—in a race to 4 stars on a new double-sided Triumph Track, so every turn is crucial.
